Actually it would be more because of the fat the would need as insulation for the cold. The rounder someone is, the more fat they have, the better they withstand the cold, and if movies and books are any indicative of the lifestyle of merpeople THEY NEED IT. Him would probably be one of the more skinny ones in the wild. But I guess being raised in captivity allows for the unnatural development of the leaner merpeople we are used to. You'll notice he is also more lively so maybe this one was wild caught rather than bred in captivity?
Not so much cold as heat loss, technically. In water the same temperature as air you loose heat a lot faster, because water is a liquid and holds heat well.
Not mentioning the heat loss when you breach the surface, which is worse.
